Palpation Versus Ultrasonography for Identifying the Cricothyroid Membrane of Distorted Neck-anatomy

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 61 (actual)
• Sponsor: Rigshospitalet, Denmark · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Accepted

Summary

Participants will be anesthesiologists, who will identify the cricothyroid membrane on a silicone model of the neck with either palpation or ultrasonography. The participants can choose either the "String of pearls" or Thyroid-Airline-Cricoid-Airline (TACA) for the ultrasonographic method to be used . The silicone model of the neck is distorted with with the larynx deviated to one of the sides to simulate a patient with neck pathology.

The participants can choose either the "String of pearls" or Thyroid-Airline-Cricoid-Airline (TACA) for the ultrasonographic method to be used . The silicone model of the neck is distorted with with the larynx deviated to one of the sides to simulate a patient with neck pathology. The test persons are randomized to use other palpation or ultrasonography. All attempts are video-taped.
